With the rapid development of the Industrial Internet of Things (IIoT), more and more industrial devices need to be connected to the network for data transmission and monitoring. Against this backdrop, the power supply method for Cellular Router has become increasingly important. As an emerging power supply technology, Power over Ethernet (PoE) is gradually gaining widespread application in Cellular Router. This article aims to explain the principles, advantages, and application scenarios of PoE power supply for Cellular Router to traditional industries.
PoE power supply technology refers to the technology that provides direct current power and data signal transmission for IP-based terminal devices (such as Cellular Router, IP phones, wireless LAN access points, etc.) through network cables without changing the existing Ethernet cabling infrastructure. It utilizes the idle pairs or data pairs in the existing Ethernet cables to transmit power, thereby achieving simultaneous transmission of power and data.
Specifically, PoE power supply technology has two power supply modes: Alternative A (signal lines 1, 2, 3, 6) and Alternative B (idle lines 4, 5, 7, 8). In Alternative A mode, power and data are transmitted through the same pair of lines (i.e., line sequence 1, 2, 3, 6), but different frequencies are used to avoid interference. In Alternative B mode, power and data are transmitted through different line pairs (i.e., data through line sequence 1, 2, 3, 6 and power through line sequence 4, 5, 7, 8).
1. Simplified Wiring: PoE power supply technology achieves the transmission of power and data through a single network cable, eliminating the need to lay separate power cables for the devices, greatly simplifying the wiring work.
2. Safety and Reliability: PoE power supply adopts a low-voltage DC power supply method, reducing safety hazards such as electric shock and fire. At the same time, since power and data are transmitted on the same network cable, it also reduces the risk of equipment theft or damage.
3. High Flexibility: PoE power supply supports hot-swapping, allowing devices to be replaced or added without shutting down the entire power system, improving system flexibility and maintainability.
4. Cost Savings: By reducing the workload of wiring and maintenance, PoE power supply technology can help enterprises save a significant amount of manpower and material costs.
As a key device connecting industrial equipment and networks, the stability and reliability of the power supply method for Cellular Router are crucial. PoE power supply technology provides the following application scenarios for Cellular Router:
1. Factory Automation: In factory automation systems, a large number of sensors, actuators, and other devices need to be connected to the network for real-time data transmission and monitoring. Cellular Router with PoE power supply can conveniently provide power and data transmission services for these devices, simplifying wiring work and improving system reliability.
2. Remote Monitoring: For remote or inaccessible locations (such as oil and gas fields, mines, etc.), Cellular Router with PoE power supply can achieve remote monitoring and data transmission functions without the need to lay power cables on-site, reducing maintenance costs.
3. Intelligent Transportation: In intelligent transportation systems, traffic monitoring equipment, signal control equipment, and other devices require stable and reliable power supply and data transmission. PoE power supply technology can provide efficient and safe power supply solutions for these devices.
With its advantages of simplified wiring, safety and reliability, high flexibility, and cost savings, PoE power supply technology has been widely used in Cellular Router. With the continuous advancement of technology and the expansion of application scenarios, it is believed that PoE power supply technology will play a more important role in the field of the Industrial Internet of Things.
